摘要：
A polarizing plate comprising a polarizer and a transparent protective film at least one surface of the polarizer via an adhesive layer, wherein an applied layer comprising a polymer having a hydroxyl group is formed on a surface of the transparent protective film that is adhered to the polarizer, and the adhesive layer is formed by an adhesive comprising an isocyanate adhesive, has no problem concerning saponification processing and has a good adhesive property between a polarizer and a transparent protective film.
